Promising review: "Every so often, you find a product on Amazon that you just have to buy because of all the positive reviews. It's amazing how great the product is once you have it in your hands. This is one of those products. My stainless-steel sink is 14 years old. Although we have been cleaning the sink every other week since moving in, we have never used this product or polished it. It made a huge difference the first time I used it on the sink. The sink shone so brightly in the overhead lights that it was almost impossible to see! This product is "doing its job" because the stainless steel will leave a black residue after cleaning. From Wyoming to California via NYCAmazon has it for only $10.03.
